He is every other inch a gentleman.

The line plays on the idiom “every inch a gentleman,” a formula of totalizing praise that asserts someone’s manners, honor, and social bearing are complete and consistent. By inserting “every other inch,” West’s phrasing (if accurately attributed) turns the compliment into a barbed half-compliment: the subject performs gentility in some respects while failing it in others. The joke depends on the measurement metaphor—character assessed like physical stature—and suggests that “gentlemanliness” can be a veneer, unevenly applied, or selectively observed. It also hints at West’s broader satirical interest in social performance and the gap between public polish and private conduct.
